BRO TGHM, OF BROOKLYN, ASSIGR TO THE STAND ARD Application filed February 24, 1SE5.

To a/ZZ whom it may coli/Gern:

Be it. known that l, srnruun 3L Benet-inni, ucitizenolthe Unite( States.residinginBrooklyn, in the eoi'inty ot' Kings und Stute ot'eu' York, have invented eert-ain new und useful Improvements in Drop-tiovenients for Pocket Utensils, ol which the following is a speciiication.

rihisinvention relates tod rop-movements,

to so-Cnlled, used chiefly t'or pocket-pencils, but also applicable to many other articles for tbe pocket-us pen-knives, button -l1ool;s, pens, tooth-picks, l'e. Such drop-movements eonsist, in general, ot" the outer tubular easing or i5 body tor housing the remaining parts, the

drop,'77 which is u lead-holder or other utensil, arranged to slide into and ont of the eas ing, and u eateli or look uttaebed to the easing and adapted to retain the holderin place when 2o either housed in or protruding troni the eas ing. t Figure 'i ot' the accompanying druu'ings it side elevation ol' :t pocket lend-pencil con` structed according to my invention, the outer easing being pnrtly broken anny to show the Working parts. und the drop or lead-holder being protruded. Fig. il is a longitudinat inidseetion et' the suine, the plane ot' the seotion being :it right angles to that in Fig. 1. "o Fig. 3 is :in inverted inidseetion of the peneil, showing the drop or pencil-holder dropped boel; into the easing. Figs. -.t and 5 are .side elevations,on a sinziller scale, shon'ingu tooth pick and button hook, respectively, constructed recording to my invention.

Referring to the drutrings, let A designate the usual tubular easing or body portion ot' the pencil or other pocket utensil; l5, the drop or moving pu1t,.rliiel1 slides in the easing, end C 4o the cup or projection zit one end ofthe easing which is depressed to release the drop.

I will iirst deseribe the eonstruetionshown in Figs. l, 2, and 3. The pencil-ease A conv sists of en outer tube, u, which is contracted or open down at its opposite ends, und an iuner tube, L, rfliieli is fixed to the outer tube ut its louer end. The inner tube, b, t'orins the slideuat' Yfor the drop il, which in this construction constitutes (or Curries) the lend-hold er oi' the pencil. This lend-holder, Whioh is of the usuel or any ordinary construction, is

eleuily shown in Figs. l and 2, and requires no description, us it l'ornis no port of my invention. The drop B is extended into the tube b :i sutiieient distance to form u suitable bee-ring by means of :t tube, c, which forms u part ot' the drop, und this tube has a pin, d, fixed to it, which Works in it longitudinal slot,

e, in the tube i), thereby liiniting` the lengthwise movement ol the drop und keeping it from turning. A. long` leut`Spring, f, which constitutes the looking-spring, is fastened to the outside ol" the tube Z) by ineaus of a rivet,

y, at one end. It is provided with two holes, h le., which coincide with the two extreme positions of the pin d :it opposite ends of the slot e. The spring f tends to bow' in the middle, or near the lower hole, it. Over the Spring at its iixed end is plueed a ring, t, which is pressed against by o spiral spring, s, coiled fo around the tube?) and Within the tube a. The upward pressure ot` this spring tends to force the ring fi up over the leef-spring f, thereby pressing the latter tlat against the tube I), as shown in Fig. 2. in this position the pin d is eonned in one or other ot' the holes lz', and the drop is thus locked in plane.

The upper end ot' the cese A is closed by the cap or but-ton @which projects beyond the end of the cose, und is inado to slide Within the eon- 8o traeted end ol the tube u. This cap is made of oi tube, k, which iits closely around the outside ofthe tube 7), and extends down to und is fastened to the ring This tube is siottedor ent away down one side, as oiearly shown in Fig. 8 l, to make rooin Yfor the springf. The eap C, tube 7.", and ring 'i thus all :nove together, and are pressed upward and the esp protruded by the spring 5. They are kept troni turning by a pin, Z, tixed in the tube b, und Working go in a slot, m, in the tube 7i'.

Figs. l and 2 shoY the drop B (or leedholder) protruded ready for the pencil to be used. lt is looked in position by the pin d being eonlined in the lower hole, iz. To draw g5 inthe lead-holder, it is necessary to invert the device and press in the Cup C, as shown in Fig. 3. rthis operation presses haelt the ring i', und disenguges the looking device by permitting the spring j to ity oi'ttwurdly, thus Ico reieusing the pin d, whereupon the drop B falls by its own weight into the cese A until the pin d is stopped at the opposite end of the slot e. This is the position shown in Fig. 3. The drop has just fallen, andthe cap VC is still depressed. On releasing this cap the spring s l'orees up the ring i again and crowds the spring f against the tube b. thus bringing its hole h over and confining the pin d. The drop B will remain thus concealed Within the case A until the cap Gis again pressed upon while the pencil is held right side up, when it will again fall out.

Fig. 4 shows'on a smaller scale the application 0f my invention to a gold tooth-pick. It is equally applicable to holders for quill tooth-picks. Fig. 5 shows its application to pocket button-hooks. In both cases the interior mechanism and the operation are the same as already described.

I am aware that drop-movements working with clanipingjaws engaging the drop on op posite sides, and operated to release the drop by the pressing in of a longitudinally-movable spring-protruded cap, are not new; and I ain also aware that a two ended instrument has been patented, havinga pencil at one end and a drop-movement working in the other end, wherein the drop is locked by a spring bearing a pin entering holes at opposite ends of a slot, and is unlocked by an arm which displaces said pin when the pencil is pressed inward.

I claim as my invention- 1. The combination of a tubular casing, A, a drop, B, sliding into oneend of said casing, a cap, O, arranged at the other end thereof', a locking-spring, f, for said drop attached to the casing and tending to spring outward away from said drop and release the latter, a locking-slide, t', connected to the cap C, and adapted to move longitudinally and to engage the locking-spring and press the saine inward, and a spring, g, acting to force said slide into engagement with said spring, substantially as set forth, whereby the pressing in of saidV cap acts to disengage said slide from the locking-spring, and thereby to unlock the drop.

2. The combination of a tubular casing, A, consisting ot' outer and inner tubes, drop B, sliding into one end ot' said casing in said inner tube, a cap, C, arranged at the other end ol' said casing, a lockingspring arranged longitudinally in the space between said inner and outer tubes and normally springing outwardly, two locking provisions on said spring at a distance apart equal to the play ot' the drop and engaging a reciprocal provision on the drop, a slide, z', adapted to move longitudinally and to engage the locking-spring and force it inward to lock the drop, tube k, connecting said slide t' to said cap C, and a spring, g, pressing said slide into engagement with the locking-spring, substantially as set forth.

3. The combination of a tubular casing, A, consisting of outer and inner tubes, drop B, sliding into one end of said casing in said inner tube, a locking-spring arranged in the space between said outer and inner tubes, and adapted to engage and lock said drop in either extreme position ofthe latter, a sliding tube, 7c, arranged in the space between said outer and inner tubes with one end extending out at the end of the casing and closed to form a cap, C, a disengaging device for the lockingspringconnected to said tube, and a spring, g, acting to press said tube and cap outward, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
